PORTABLE CORN-CRIB.

SPECIFICATION forming part of Letters Patent No. 450,505, dated April14, 1891.

I Application filed July 7, 1890. Serial No. 357,974. (No model.)

To all whom it 71mg/ concern:

Be it known that we, CHARLES IRA COOK and HENRY M. BRITTON, both ofOdebolt', in the county of Sac and State of Iowa, haveinvented a new andImproved Portable Corn- Crib, of which the following is a full, clear,and exact description.

Our invention relates to improvements in portable corn-cribs, and isintended as an improvement on the corn-crib for which Letters Patent No.426,714 of the United States were granted to us April 20, 1890.

The object of our improvement is to make the crib more substantial, toprovide more thorough means of ventilation, and to provide means wherebythe crib may be more easily filled or emptied.

To this end our invention consists in certain features of constructionand combinations of parts, which will be fully described hereinafter,and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all thefigures.

Figure 1 is a front elevation of the device. Fig. 2 is a horizontalcross-section on the line x of Fig. 1. Fig. 3 is abroken detail view,partly in section, showing the lower door open and the rack in positionto guard the door. Fig. 4 is a detail side elevation of the ventilator,and Fig. 5 is a detail perspective view of the trough for connecting thelower end of the ventilator with the outer air.

The body A of the crib is cylindrical in form, and is composed of aseries of vertical slats A', as shown in our former patent abovereferred to; but instead of connecting the slats by wires, suit-ableblocks a are placed between every two slats a convenient distance apartand cables t are passed through the slats and blocks, said cables havingat one end a suitable nut or head, and having at the other end asuitable thumb-nut b', so that by manipulating the nut the slats A maybe tightened or loosened. The body is held together in the mannerdescribed in our former patent-that is, by chains c, having suitablehooks c', the chains being passed around the two outer slats of thebody. A

door B opens through the upper portion of the body, said door beingformed by sawing off two of the slats A', connecting said severedportions together, and hinging them to 55 the adjacent slats. Incarrying out this idea any suitable hinges may be employed, or the doormay be allowed to swing on the cables. Asimilar door B is arranged in asimilar manner in the lower portion of the crib, and 6o other doors maybe provided it' necessary or desirable. The body portion A is mountedvertically upon a suitable floor D, composed 'of parallel slats D,having suitable blocks d between them, and having rods el extending 65transversely through the slats and provided with suitable thumb-nutscl2, by means of which the slats may be tightened together.

It is obvious that instead of rods cables may be used, or the slats maybe attached together 7o in any convenient way'.

A post E is planted in the ground so as to extend vertically through thefloor D, and secured to the upper end of the post are the vertical slatsE', which are separated by suit- 75 able blocks e., and which extendupwardly through the body A of the crib, thus forming a convenientventilator. The ventilator is surmounted by a conical top formed bytheconverging pieces E2, which forms a conven- 8o ient support for thecrib-cover. The top of the ventilator is connected with the top of thebody A by suitable braces F, said braces having, preferably, ahookand-eye connection with the ventilator-top and with the crib- 85body. The braces F will thus afford a convenient support for the coverGr, which is made, preferably, oi' canvas, but may be made of anysuitable material, and which extends from the ventilator-top to thesides of the 9o crib, being secured thereto in any convenient way. Inpractice we find four braces F to be a convenient number; but it isobvious that the number may be increased or diminishedwithoutdeparting-trom the principle of 9 5 our invention.

An inverted -V-shaped trough H yextends from the outer portion of thecrib-body to the bottom of the ventilator, thus permitting the air tocirculate freely through the same and roo aiord an additional means ofVentilation. It is not essential that the trough should be V- shaped, asany suitable trough may be employed which Will serve as anair-conductor.

The rack J is placed over the door B', so as to prevent the corn fromfalling too rapidly through the door when the door is open, the saidrack being composed of the inner slats j and the side strips j. The rackhas an inwardly-inclined face and an opening J near the bottom, the saidopening being sufficiently large 'to permit the corn to pass through thesame, so t-hat it may be easily shoveled up.

The crib is filled with corn by shovelingthc corn in at the top throughthe door B, and is emptied by removing the corn through the l lower doorB.

While the device described above is intended chieiy for use as acorn-crib, it is obvious that it may be used for storing coal or anyother article. lt is advisable to use the ioor D in connection with thecrib; but it is obvious that the body A might be mounted directlyuponthe ground and be used as a crib.

Having thus described our invention, We claim as new and desire tosecure by Letters l Patent- .l

l. A portable crib comprisinga cylindrical body formed of a series ofspaced slats connected together by cables passing through them andhaving an upper and lower door, a ventilator formed of vertical andspaced slats secured together, a cover, and an inclined rack oppositethe lower door and having an opening in its lower portion, substantiallyas herein shown and described.

An improved portable crib consisting of a slatted floor, a cylindricalbody formed of a series of vertical slats, spacing-blocks and cablespassing through said slats and blocks, said body being provided withdoors, a ventilator formed of a post, vertical slats and spacing-blocksbetween the slats, a cover, an inclined rack opposite lower door andhaving an opening in its lower portion, and an air-conductor extendingfrom the ventilator to the side of the crib, substantially as hereinshown and described.
